tricylic intermediate 3a, for the total synthesis of the C20-nor analogue of salvinorin A, was prepared in seven steps from 3-furaldehyde. Key steps involved a highly regio- and diastereoselective Lewis acid assisted Diels−Alderreaction followed by base-promoted epimerization and a completely stereoselective conjugate reduction.
